ABSTRACT
This study was conducted to investigate the effects of in ovo injection of methionine (Met) and/or disaccharide (DS) on post-hatching pectoral muscle and small intestine development, glycogen reserves, jejunum morphology, and jejunum digestive enzymes activities. A total of 600 fertilized eggs containing live embryo from geese were randomly assigned into 4 groups with 6 replicates and 25 eggs per replicate in a completely randomized design employing a 2 × 2 factorial experiment. Factors in 4 groups included noninjection, Met injection (5 g/L Met + 7.5 g/L NaCl), DS injection (25 g/L maltose + 25 g/L sucrose + 7.5 g/L NaCl), or DS plus Met injection (25 g/L maltose + 25 g/L sucrose + 5 g/L Met + 7.5g/L NaCl), respectively. In ovo nutritional injections were performed at day 23 of incubation, and the experiment until d 21 post-hatching. We found that in ovo feeding of Met increased relative weight of pectoral muscle and small intestine, jejunum alkaline phosphatase activities, and jejunum villus height and surface area. DS injection improved the relative weight of pectoral muscle, pectoral and liver glycogen contents, jejunum villus height, width, and surface area, and jejunum sucrase, Na+/K+ATPase, and alkaline phosphatase activities. In addition, Met plus DS injection synergistically improved jejunum villus height and surface area. Therefore, Met plus DS injection is a suitable strategy for improving intestinal parameters in gosling during post-hatching periods.
